Subject [jira] Resolved: (JS2-873) Simplified parent-child relationship model for Roles and Groups
Date Tue, 07 Oct 2008 23:36:44 GMT

     [ https://issues.apache.org/jira/browse/JS2-873?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ate Douma resolved JS2-873.

    Resolution: Fixed

The brand new portal trunk (copied over from the security-refactoring branch) now provides
a new and (extremely) flexible, extendable and pluggable Principal Associations solution
which provides all the features described, and then some :)

> The current Jetspeed security role/group model *technically* supports a hierarchical
> In practice though, this isn't used really, nor do the j2-admin portlets support it through
the UI.
> Furthermore, the hierarchical relationship is based on a specific (preferences) hierarchy
naming which really doesn't fit well (better said: not at all) with a backend like LDAP.
> The current model simply cannot be used with LDAP for using role-group relationships.
> A typical use-case requiring a more simple and straighforward solution:
> - defining organisation divisions and subdivisions as groups and defining a parent-child
relationship between them
> - a user belonging to a division group then also belongs to any subdivision group of
that division
> - the same goes for roles, the user could automatically inherit the roles assigned to
the subdivision group. 
> As AFAIK the hierarchical relationship model isn't used at all right now, this issue
will resolve its complexity and limitation by replacing it with "flat" parent-child relationships:
> - only support non-hierarchical groups and roles
> - allow a group or role needs to be defined as child of another group or role
> - just need a security-role-role and security-group-group table (and corresponding LDAP
> - check/enforce no circular references can be created
> - adding UI support for this will be rather easy: we already have support for the group-role
relationships, this is just more of the same
